Should you EQ above 500Hz, or should room correction stop at bass frequencies? It's one of the most debated topics in home theater calibration, and the answer isn't as simple as many people think.
In this video, I explain what EQ curtains are, why so many people recommend limiting correction to around 500Hz, and why I sometimes choose full-range correction instead. We'll compare measurements, discuss speaker matching, system integration, object panning, and look at real-world examples to help you decide which approach makes the most sense for your own system.
As always, there isn't a one-size-fits-all answer. The best EQ curtain depends on your room, your speakers, and your goals.
